Definitions
- the present invention relates to a spinning position of a ring spinning machine, with a drafting system for drafting a fiber structure, which has at least one pair of exit rollers, a ring located on a ring rail, a ring traveler rotating on the ring and a spindle arranged on a vertically moving spindle rail.
- Spinning stations for ring spinning machines are widely known in the prior art. Especially in the field of so-called multi-balloon spinning with a large number of balloons, it could be shown that low-end-break operation with consistently good yarn quality can be achieved.
- GB 1 237 944 shows a method for producing yarn using a ring spinning machine, in which a spiral path of the fiber structure with at least two balloons is created between the clamping point of the outfeed rollers and the ring traveler.
- the method has a fixed element and a movable element constraining the balloon.
- the ring rail moves over the entire length of the spindle, the number and size of the balloons changes disadvantageously. This change leads to a large variance in the yarn tension.
- DE 10 2016 117 364 A1 shows a ring spinning machine with a vertically movable spindle rail.
- the ring spinning machine is designed in such a way that the ring is arranged in a stationary manner on the ring spinning machine.
- a balloon ring is disclosed which, like the ring, is stationary.
- the spindle rail can be held temporarily. So the spindle bank z. B. blocked vertically in the lowest position during the deduction of the full cops.
- the locking device arranged according to the invention can release the spindle rail again so that it can move freely again vertically and the spinning process can be continued undisturbed.
- This construction of the ring spinning machine can block and/or impede the exchange of a full cop for the empty yarn tube or the doffing, in particular by the balloon ring.
- the CH340167A shows a ring spinning machine with a balloon constriction ring arranged between the upper thread eyelet and the ring rail.
- the teaching contained therein should also help to be able to remove balloon constriction rings with a smaller diameter than the spinning ring from the spindle after a cop has been fully spun without a great deal of design effort on control means.
- the balloon constriction ring can be swiveled over the uppermost edge of the yarn carrier located on the spindle in any spindle position.
- the document describes an embodiment of a ring spinning machine in which a thread eyelet and a balloon constriction ring are mounted on a movable spindle rail by means of rods and follow the movement of the spindle rail.
- DE4128523C1 shows a method for attaching roving or yarn to a ring spinning machine.
- the document describes that in a piecing process, the fiber structure is thickened within a specific thread section, as a result of which this thread section has a greater mass per unit of length, which when spinning the thread at the spinning station of the ring spinning machine due to the higher centrifugal forces that occur results in a thread balloon with a larger diameter and thus lead to yarn breaks in some cases.
- the document proposes to limit the suture balloon with an additional balloon limiting ring during an attachment process. Zen.
- a maintenance device that can be moved along the spinning positions of a ring spinning machine is proposed, on which an additional balloon limiting ring that can be advanced to a spinning position during a piecing process is arranged.
- DE1150911 B discloses a spinning machine with a carriage that can be moved parallel to the spindle axis and to which the thread guide and balloon limiting rings are attached so that they can pivot about a particular axis. This is intended to remove the thread guide and the balloon limiting rings from the finished bobbins in a simple manner and with one hand movement and for all bobbins at the same time. To this end, it is proposed that the carriage should be pulled up vertically by means of chains or cords and that a simultaneous folding of the thread guide and balloon limiting ring be initiated by striking an upper frame part of a spinning machine frame.
- the object of the present invention is to eliminate the disadvantages known from the prior art.
- the task is in particular to create a spinning position of a ring spinning machine which keeps the yarn tension essentially constant, facilitates doffing of the full bobbins and/or ensures stable operation of the spinning positions with a constant number of balloons.
- the object is achieved by a spinning station of a ring spinning machine, a ring spinning machine and a method for operating a spinning station of a ring spinning machine with the features of the independent patent claims.
- a spinning position of a ring spinning machine is proposed, with a drafting system for drafting a fiber structure, which has at least one output roller pair, a ring located on a ring rail, a ring on the ring traveler and a spindle arranged on a spindle rail that moves vertically, in particular during the spinning operation.
- the fiber bundle leads along a spiral path from the pair of output rollers of the drafting system to the ring traveler.
- the spiral path forms at least two balloons.
- the fiber structure is guided through the ring traveler, whereby the fiber structure is rotated and a yarn is produced, which is wound onto a sleeve that is placed on the rotating spindle.
- the sleeve can have a predetermined diameter and a predetermined length.
- the vertically moving spindle rail moves in the vertical direction relative to the machine frame and/or the ring rail. Due to the vertical movement of the spindle rail to the ring traveler guided on the ring, the tube can be filled with the yarn and a bobbin can thus be formed until a full bobbin is formed.
- At least one balloon constriction ring is arranged between the pair of output rollers and the ring rail, the at least one balloon constriction ring having a joint.
- the balloon constriction ring can specify and/or influence at least the diameter and/or the height of at least one of the balloons, in particular by constricting and/or spatially limiting the movement.
- the yarn tensions can be kept constant to a large extent.
- the balloon constriction ring can be moved from an operating position into a removal position by means of the joint. In the operating position, the spinning station is operated and thus at least one of the balloons is constricted by the balloon constriction ring.
- a full cop can be removed from the spindle and/or an empty tube can be placed on the spindle.
- the thread tension in the balloon adjacent to the sleeve can be specifically increased by means of the balloon constriction ring and the height of the same balloon can thus be adapted to the length of the sleeve.
- the diameter of the balloon constriction ring is smaller than the diameter of the ring and/or larger than the diameter of the, in particular intended for yarn take-up, sleeve is.
- the diameter of the balloon constriction ring is at least 30 mm and at most 50 mm.
- At least one further balloon constriction ring is arranged between the pair of output rollers and the ring rail.
- the additional balloon constriction ring is advantageously spaced vertically from the balloon constriction ring.
- the diameter and/or the height of at least one of the balloons can be predetermined and/or influenced by means of the further balloon constriction ring. In this way, an even more constant yarn tension can be achieved, particularly in the area between the further balloon constriction ring, which is arranged closer to the drafting system, and the drafting system.
- the balloon constriction ring and/or the further balloon constriction ring by suitably positioning the balloon constriction ring and/or the further balloon constriction ring, contact of the not yet completely spun fiber structure with the sleeve and/or with neighboring spinning points can be reliably avoided. It is advantageous here if the two balloon constriction rings are arranged centrally above the ring. Because of the further balloon constriction ring, an alternative balloon shape can be produced which has proven to be relatively extremely robust. This can also bring about a more even yarn quality.
- the number of balloons can be kept constant and/or the spinning position can be kept as compact as possible in the vertical direction by means of the additional balloon constriction ring. A compact design of the spinning position in the vertical direction improves the operability of the spinning position and thus of the ring spinning machine.
- the diameter of the further balloon constriction ring is smaller than the diameter of the ring and/or larger than the diameter of a sleeve provided for receiving the yarn. Furthermore, it is advantageous if the diameter of the additional balloon constriction ring is at least 30 mm and at most 50 mm. It has been shown that an optimal balloon shape can be created for a large number of fiber assemblies.
- the additional balloon constriction ring has an additional joint. This can also make doffing easier.
- the additional joint can be a hinge arranged at the spinning station for moving the additional balloon constriction ring of the spinning station and/or a shaft spanning the spinning station for moving several additional balloon constriction rings of adjacent spinning stations. Thus, at a large number of spinning stations, the respective additional balloon constriction ring can be folded over by means of the shaft in the direction of the drafting system or in the direction of the ring rail.
- the ring rail is stationary during spinning. Fixed here means that the ring rail is vertically stationary during spinning.
- To wind the yarn onto a tube on the one hand an alternating vertical movement and on the other hand a constant vertical movement between the spindle with the tube placed on and the ring rail is necessary as the filling of the tube increases.
- the relative movement of the sleeve to the ring rail in the positive and negative vertical direction is to be understood as an alternating vertical movement.
- the positive vertical direction is from the ring rail towards the drafting system.
- the negative vertical direction is opposite to the positive vertical direction.
- a constant vertical movement is to be understood as the relative movement from the spindle with the sleeve placed on it to the ring rail only in a positive or negative vertical direction.
- At least one of the vertical movements is carried out by the vertically moving spindle rail.
- the ring rail is designed to be stationary during spinning, both vertical movements—the alternating vertical movement and the constant vertical movement—are carried out by the spindle rail. Due to the fixed design of the ring rail, it can be manufactured more simply and thus more cost-effectively.
- such a device has the advantage that the constant distance between the drafting system and the ring rail means that the size and/or shape of the balloons remains the same compared to conventional functional spinning machines. This leads to a significantly increased stability of the balloons during the spinning process compared to the previously known systems.
- the balloon constriction ring which is arranged closer to the ring rail has a first distance from the ring rail which is smaller than the length of a sleeve, the length of the sleeve being predetermined.
- the balloon which is arranged closer to the ring rail, is shaped in such a way that contact between the not yet completely spun fiber structure and the sleeve is avoided, as will be explained in more detail in connection with the following drawings. If the vertically moving spindle rail is in the upper end position, the sleeve protrudes beyond the balloon constriction ring. Due to the design of the balloon constriction ring with a joint according to the invention, the space required for doffing can continue to be guaranteed. It is also advantageous if the first distance is at least 70 mm and at most 130 mm.
- At least one of the balloon constriction rings preferably the other balloon constriction ring which is arranged closer to the drafting system—has a second distance from the ring rail which is greater than the length of the sleeve, the length of the sleeve being predetermined.
- at least one of the balloons can be designed in such a way that the fiber structure does not come into contact with the tube and/or with the neighboring spinning station. Due to the greater distance to the ring bench, the necessary Space required for doffing and/or for pivoting can be ensured by the additional joint.
- the second distance is at least 150 mm and at most 240 mm.
- a third distance between two balloon constriction rings is smaller than the first distance between the balloon constriction ring, which is arranged closer to the ring rail, and the ring rail.
- the further balloon constriction ring which is arranged closer to the drafting system, is arranged directly after the exit roller pair in the conveying direction of the fiber structure.
- at least one of the balloons can be specified and/or influenced immediately after the pair of output rollers in terms of its diameter and/or its height.
- At least one of the two balloon constriction rings is stationary during spinning. Particularly good results can be achieved when both balloon constriction rings are stationary during spinning.
- Fixed here means that the two balloon constriction rings stand still vertically during spinning. The diameter, height and/or number of the balloons can thus be formed as uniformly as possible. This leads to yarn tensions that are as constant as possible and/or sufficiently stable operation of the spinning station.
- a spinning position according to the invention or a ring spinning machine according to the invention equipped with such a spinning position—can be manufactured and operated particularly inexpensively due to the smaller number of components to be moved.
- the two balloon constriction rings are firmly connected to the machine frame or frame during spinning.
- the balloon constriction ring and the further balloon constriction ring are arranged on the machine frame of a ring spinning machine.
- the two balloon constriction rings of such an embodiment are preferably mechanically fixed to the machine frame.
- At least one of the balloon constriction rings preferably the balloon constriction ring which is arranged closer to the ring rail—has an opening which is larger than the diameter of the sleeve, the diameter of the sleeve being predetermined.
- the sleeve placed on the moving spindle rail can be moved by the balloon constriction ring.
- At least one of the balloon constriction rings is composed of at least two segments.
- the at least one balloon constriction ring can be brought into external contact with the fiber structure during the spinning operation or with the sleeve or a thread wound on the sleeve during doffing.
- the shape of the thread balloon can be changed during certain phases of the spinning operation, and thus the stability of the operation, the productivity and the quality of the yarn produced can be improved.
- such an embodiment permits simplified doffing, since the balloon constriction ring and/or the further balloon constriction ring do not impede the replacement of full tubes with empty tubes. Due to the composition of at least two segments - as can also be seen from the following drawings and associated explanations - complex displacement mechanisms known from the prior art for balloon constriction rings can be avoided. This represents a significant simplification and also reduces the energy costs in the spinning operation, especially in modern ring spinning machines with often more than 1600 spinning positions.
- At least one of the segments is arranged on the joint. At least one of the segments can thus be moved by means of the joint.
- the joint is advantageously arranged in such a way that at least one of the segments can be moved away from the sleeve and/or away from the axis of rotation of the spindle of the spinning station and/or towards the neighboring spinning station, as will be explained in more detail in connection with the following drawings. This can also make doffing easier.
- the segments are designed to be removable from one another in order to enlarge the opening, in particular with the aid of the joint.
- the segments can be designed to be removable from one another in such a way that a filled cop arranged on the spindle and/or an empty tube with its diameter can be removed horizontally, in particular at a position in the vertical direction, between the segments.
- at least one of the balloons can be specified and/or influenced in terms of its size and/or shape, the number of balloons and/or the yarn tension.
- the first and/or second distance of at least one of the balloon constriction rings to the ring rail is adjustable.
- at least one of the balloon constriction rings can be adjusted at a distance from the ring rail such that the yarn tension and/or the number, the diameter and/or the height of the balloons is constant.
- a ring spinning machine with at least one spinning position is proposed. The spinning position is designed according to the above description, it being possible for the features mentioned to be present individually or in any combination.
- a fiber structure is drafted in a drafting system and leaves the drafting system after a pair of exit rollers.
- the fiber structure is guided through a ring traveler running around a ring.
- the fiber strand is twisted, creating a yarn, and the yarn is wound onto a tube that is placed on a rotating spindle.
- the spindle is arranged on a vertically moving spindle bank and a spiral path of the fiber structure with at least two balloons is created between the pair of exit rollers and the ring traveler.
- the spinning position is advantageously designed in accordance with the preceding description, with the features mentioned being able to be present individually or in any combination.
- the spiral path of the fiber structure is narrowed by at least one balloon narrowing ring and the balloon narrowing ring is moved from an operating position to a removal position, particularly when removing the sleeve and/or the cop from the spindle.
- FIG. 1 shows a schematic side view of a spinning position according to the invention with a balloon constriction ring in an operating position and with a spindle rail in a first position
- FIG. 2 shows a schematic side view of a spinning position according to the invention with a balloon constriction ring in an operating position and with a spindle rail in a second position and
- FIG. 3 shows a schematic side view of a spinning position according to the invention with a balloon constriction ring in a removal position and with a spindle rail in a third position.
- FIG. 1 shows a schematic side view of a spinning station 1 according to the invention with a balloon constriction ring 2 in an operating position and with a Spindle rail 3 in a first position.
- a large number of spinning stations 1 arranged next to one another form a ring spinning machine, not shown.
- the spinning station 1 is operated and thus at least one of the balloons 4 is constricted by the balloon constriction ring 2 .
- the spindle rail 3 is a vertically movable spindle rail 3 which is in the first position in the illustration shown.
- the first position is one of many positions that the spindle rail 3 can assume in the vertical direction VR.
- the spinning station 1 has a drafting system 5, which drafts a fiber strand 6 as it passes through.
- the drafting system 5 consists of three pairs of rollers, namely an input roller pair 7, a strap roller pair 8 and an output roller pair 9.
- the fiber strand 6 entering the drafting system 5 is drawn between the rollers of the roller pairs 7, 8 and 9.
- the fiber structure 6 leads along a spiral path from the pair of output rollers 9 to a ring traveler 11 rotating on a ring 10.
- the ring 10 with the rotating ring traveler 11 is located on a ring rail 12.
- the ring rail 12 is fixed, in particular on a machine frame 13 arranged, ring rail 12 formed.
- the spiral path is formed from at least two balloons 4 .
- the vertically moving spindle bank 3 comprises a rotating spindle 14 on which a sleeve 15 is fitted.
- the rotating spindle 14 is driven during the spinning operation by a spindle drive, which may advantageously be a single spindle drive.
- the sleeve 15 has a predetermined diameter DH and a predetermined length LH.
- the fiber structure 6 is guided through the ring traveler 11, whereby the fiber structure 6 is rotated and a yarn 16 is formed, which is wound onto a rotating sleeve 15. Tracing the yarn 16 onto the sleeve 15 requires alternating vertical movement and constant vertical movement.
- the spindle rail 3 moves alternately in positive and negative vertical directions VR. This creates the layer structure of the yarn 16 on the tube 15. With increasing yarn filling of the tube 15, the spindle rail 3 moves constantly in the negative vertical direction VR and thus away from the drafting system 5.
- the spinning station 1 has another balloon constriction ring 17 .
- the further balloon constriction ring 17 is spaced from the balloon constriction ring 2 in the vertical direction VR.
- At least one of the balloons 4 can be predetermined, influenced and/or narrowed by the two balloon constriction rings 2, 17 in such a way that the fiber structure 6 does not hit the sleeve 15 and/or a cop 23 in the course of its spiral path.
- the balloon constriction rings 2, 17 also each have an opening 18.
- the sleeve 15 projects through at least one of the balloon constriction rings 2, 17, in particular through the balloon constriction ring 2, the diameter or the open area of the opening 18 is larger than the diameter DH of the sleeve 15 the first distance A1 from the balloon constriction ring 2 to the ring rail 12 is less than the length LH of the sleeve 15.
- the second distance A2 from the further balloon constriction ring 17 to the ring rail 12 is greater than the length of the sleeve 15 in the exemplary embodiment shown. It is therefore not necessary here, but how shown here possible that the opening 18 of the further balloon constriction ring 17 is larger than the diameter DH of the sleeve 15.
- a third distance A3 between the balloon constriction ring 2 and the further balloon constriction ring 17 is smaller than the first distance A1 between the balloon constriction ring 2 and the ring rail 12.
- the balloon constriction ring 2 is formed from a first segment 21 and a second segment 22 .
- the two segments 21 , 22 together form the opening 18 of the balloon constriction ring 2 .
- each of the segments 21, 22 defines a part of the opening 18.
- the two segments 21, 22 are connected by means of a Joint 19 connected to each other and arranged on the machine frame 13.
- the additional balloon constriction ring 17 can also have an additional joint 20, as shown here.
- the further balloon constriction ring 17 is shown in the exemplary embodiment shown here as being formed in one piece. Thus, only the further balloon constriction ring 17 is moved to the machine frame 13 by means of the further joint 20 .
- the balloon constriction ring 2 and the further balloon constriction ring 17 are shown in the operating position.
- FIG. 2 shows a schematic side view of a spinning position 1 according to the invention with a balloon constriction ring 2 in an operating position and with a spindle rail 3 in a second position.
- the distances A1, A2 and A3 as well as the diameter DH and the length LH of the sleeve 15 are not shown in FIG. However, these are identical.
- the sleeve 15 is largely filled with the yarn 16 .
- the spindle rail 3 is thus in the second position in the vertical direction VR.
- the yarn 16 can thus be wound up in the upper area of the sleeve 15 . It can be seen from FIGS.
- the spindle rail 3 lowers downwards in the vertical direction VR as yarn filling progresses. This can also be referred to as constant vertical motion.
- the alternating vertical movement for the layer build-up is also ensured by the moving spindle rail 3 due to the stationary ring rail 12 . It is also conceivable in an alternative embodiment that the alternating vertical movement to build up the layers of the yarn 16 on the tube 15 is realized by a vertically moving ring rail 12 .
- FIG. 3 shows a schematic side view of a spinning position 1 according to the invention with a balloon constriction ring 2 in a removal position and with a spindle rail 3 in a third position.
- the third position of the spindle bank 3 is the position in which the sleeve 15 or a completely filled cop 23 is displaced as far as possible upwards in the direction of the drafting system 5 in the vertical direction VR. This enables easy doffing of the filled cop 23.
- the further balloon constriction ring 17 is also arranged in the removal position.
- the balloon constriction ring 2 and thus the segments 21, 22 are deflected by means of the joint 19 and the additional balloon constriction ring 17 by means of the additional joint 20 in the exemplary embodiment shown such that the cop 23 can be removed during doffing.
- the balloon constriction ring 2 was pivoted away from the cop 23 by means of the joint 19 .
- the pivoted segment 21 is shown in FIG. 3, which is located behind the cop 23 in the plane of the page.
- the pivoted segment 22, shown non-pivoted in Figures 1 and 2 would be in front of the cop 23.
- the other balloon constriction ring 17 is pivoted upwards in the direction of the drafting system 5 by means of the joint 20 .
- the joint 20 is in this case, for example, a shaft running in the plane of the page, which extends over a plurality of spinning positions 1 arranged next to one another.
